Random
This is the distance traveled by a car before the driver starts to hit the brakes.
If two forces act equally, but in opposite directions they are said to be ____________ forces
What is balanced?
If a plane travels 1000 km in 2hrs from Indianapolis to Orlando, FL, this is its' velocity.
What is 500 km/hr south?
Newton's 2nd law of motion relates force, mass, and acceleration using this formula?
What is force = mass x acceleration?
An object with a mass of 8 kg is acted upon by a 16 N force to the right. What will its acceleration be?
What is 2 m/s2?
If an object speeds up from one velocity to another, it is said to have demonstrated this.
What is acceleration?
If one force is greater than the other, the net force is said to be this.
What is unbalanced?
What can we find with the gradient of a distance vs time graph?
speed of an object
For Newton's 2nd law of motion, it is suggested that an object with a greater mass will require a greater______ to act upon it.
What is force?
Assuming an object has a mass of 5 kg and a velocity of 14.2 m/s, what is its momentum?
What is 71?
This term can be used to describe the tendency for an object to stay in motion.
What is momentum?
Tom pushes a table with a force of 6 N to the left. Tina pushes the table with a force of 12 N to the right. The table has a motion in this direction with this amount of net force.
What is 6N accelerating to the right?
What does a distance vs time graph with a straight (linear) line indicate about a moving object?
It's moving at a constant speed
Newton's 3rd law of motion relates the relationship between two forces and can be summed up by these two words.
What is action-reaction?
Final Velocity = 50 m/s south Initial Velocity = 60 m/s south Time to change velocity = 5 seconds What is the acceleration of this object?
-2 m/s2, south
What is the formula for acceleration?
Acceleration = Final Velocity - Initial Velocity / change in time with a direction
What is a scaler?
What does a horizontal line in a distance graph indicate?
The object is at rest (no movement)
This term can be classified as balanced or unbalanced based upon the net calculation.
What is resultant force?
If an object is moving to the left at a speed 5 m/s and a wind with a force of 2N is acting in front of it and behind it, this will happen to its velocity.
What is nothing? It will maintain it's motion because the net force is 0!
What is the formula to calculate spring constant?
What is a vector?
What is a measurement with size and direction?
What does a horizontal line on an speed vs time graph indicate?
The object is traveling at a same (constant) velocity
What are three ways we can tell if something is accelerating?
speeding up slowing down changing direction
Calculate the spring constant of a spring that has 10 N of weight hanging on it and an extension of 2cm.
